' Application filed August 20, 1915. Serial No. 46,450.

To all whom it may concern 7 Be it known that I, WILLIAM R. CHITTEN- DEN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Mechanical Movements; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheets of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates generally to improvements in mechanical movements and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described and then pointed out in the claims.

While in its essentials my invention is adapted for the crushing of rock in general and the reduction of quartz and adobe ore in particular, still the said invention is capable of much wider application in its ramifications as will more fully appear.

Broadly speaking, I employ a rocker bed adapted for oscillation upon a substantially plain surface. Erected upon the rocker bed are a pair of perpendicular arms, at the outer ends of which are pivoted a shaft parallel or substantially so, to the rocker bed between said arms, and, suspended from said shaft is carried an oscillatable weight. The rocker bed already mentioned is of an arc having its center coinciding with the center of said shaft, so that if said arms be oscillated at their upper ends a shifting of the axis of oscillation of the suspended weight is caused to take place; a rocking motion of the bed plate induced, and a decided oscillatory motion of the suspended weight created. The reciprocation of the perpendicular arms of the rocker bed will restore the moving inertia of the suspended weight and will maintain its oscillation thereof within certain limits. In the drawings hereinbefore referred to and made 'a part hereof,'Figure 1 is a vertical, longitudinal section of my invention, taken online 11 of Fig. 2, the extreme oscillation of the rocker bed and its perpendicular arms and the suspended weight heing shown in dotted lines. Fig. 2is a vertical, transverse section of my invention on line 2-2 of Fig.1. Fig. 3 is a transverse, vertical section'of-a fragment of my invention on line 3-3 of Fig. 1. Fig. 4 is a like section on line 4:4of Fig. 1, showing the section of the rocker bed plate in full section 'insteadof dotted linesas in Fig. 1. Fig. 5

is an end elevation ofmy invention discloslng mechanical means for reciprocating the rocking'arms forming part of my disclosure, and Fig. G is, in part, an'elevation and, in part, a section of the same on line 66 of F ig. 5. F ig. 7 denotes aschematic fragmentary side view, showing a modified form of mechanical rocking means.

Like parts are designated by corresponding symbols or characters of reference in all the figures of the drawings.

In the preferred mode of carrying out my invention, there is employed a preferably rectangular base frame A having side walls B and B, medially of the length of which are provided vertical slots G and C for purposes hereinafter more fully set forth. The said base frame has end walls D and D,

Fig. 1, which are of lesser height than the side wallsB and B, and has an open interior through the same, vertically. Surrounding the interior faces 'of the side walls B and B and D and D, at a proper elevation, are ledges or lips 10 and 10* and 11 and 11 and a transverse rib 12, upon which ledges or lips rest a plurality of crushing plates 13', which plates arepreferably plain "upon their upper surface, both longitudinally and transversely and are a snug fit upon the ledges aforesaid,between the walls B and B and Dand D,'to prevent movement thereof in said frame A.

Adapted for a rockable and slight endwise movement upon the crusher'plates 13, within the confines of the side walls Band B and D and D, is located a rocker bed E having medially of its'length, upon its opposite sides, rollers Fflpivotedupon studs G, which rollers are constructed for upward movement in the'slots C and C already referred to. Arising perpendicularly from the said rocker bed E, medially of its length, and from opposite sides thereof are arms F and F, which arm's are secured at their lower ends to said rocker bed E,and at their upperflextremities are pivoted to a transverse Shaft G. The 'lower'sqrface of this rocker with the axis of said'shaft G; and this arce I V jtravelby upright sides E and E of the memberA are four posts 50 and 60, the said bed is arcuate, having its center coinciding uate surface, rolling on the plane'surfac'e of the crusher plate 13, wagon wheel fashion, as it were, will cause the upper'ends of said upright arms F, F, to. reciprocate, or swing," like an inverted pendulum, as will herein-f:

after more fully appear.

- ,Suspended from the shaft G by means of a rod or bar H, there is a weightrJ,'which is 7 adapted to oscillate between the perpendicular arms F and-F, and to be guided in its rocker bed E as clearly seen in Figs. "1, 2, 3

' and 41 Arising fromthe four corners of thebase posts 50 and 60 being connected together by horizontal,longitud nalbraces 51 and 52 at the upper end of said posts and by like braces 53 and 5.41, intermediate the height of i 7 said posts, the same being provided to maintain said posts and '60 in an upright, par allel position with respect to each other.

Laterally connecting the posts 50 with the posts are braces 55'and 56 located at the 7 a proper height to provide a handle'member 62, whereby the said perpendicular member and its corresponding membersF or {F, as the case may be, maybe reciprocated by. a person located or stationed upon said'platform 61. It will thus be observed that a person stationed upon the platform 61 may by properly manipulating the handle 62, oscillatethe bars F, F, and thereby also cause the oscillation ofthe weight J and to maintain the latter in constant oscillation by a mere moving of the handle 62 in an evident manner. j a

The crushing p1ates13, lodged on the lips 10, 10 11 and 11 on the interior of the rectangular base A, are provided with a series of perforations 70, these-perforations being a i of largest diameter'near the ends D and D of the ends of the :base frameAland gradually" decreasingin size toward'the'longitw' crushed ispermitted to flow upon theu'pp'er:

= surface of the'crusher plates 13 and it is." herev pointed out that the side wings E or.

' E, stop the. flow ofsuch-material upon said dinal center ofsaid frame, asat 71. 'And,

' perforating the'side's Band B neartheends D and D are openings 7K, supplied with chutes L, through which" material to be 'surfaceswhenthe outer ends of the r0cke1 plate E approach contact with the, crushing p1ate'13. V I o V r r jlt is'evident that the chutes L may be connected with a-common material hopper (not shown) whereby the material passing through said chutes maybe fed thereto, or,

if the material be ina pile, shovelers may transmit the same from said pile or piles to saidfchutes. It is likewise obvious that as the material to be crushed flows upon the top face of the crusher plates 13, the forward "and backward movement of the'rocker bed E, inducedby the oscillation oftheweight J, will crush rock located between said bed E an d crusher plates 13, and will'force the same through the openings 7 0, 71to screens below, (not shown) wherein the crushed stone maybe properly screened and delivered to suitably locat'edbins.

Attention is 'now directed to the fact that the entire weight of the rocker bed E, its perpendicular arms F and F; the suspending rod H, and the oscillating weight J, is effective as a crushing Weight for the material upon the crushing plates 13, and all that is necessary to maintainthe oscillation "of the weight J, is the movement of the axis of oscillation thereof :from X to Y, Fig. 1, .by a person manipulating or moving the upper end or handle 62 from one extreme to the other, the limit of oscillatory or vibratory movement of the arms F and F being controlled by stops 99 and 99* on the longi- *tudinal members 51 01 52, as clearly shown in Fig. 1. v r

If it be desired'to pulverize the material to aline state of disintegration, I discard the series of holes of the crushingplates 13, and retain only the openings 71 located near the center of said crushing plates, so that the repeated-.rockings of the rocker bed IE will "pull as itwere, the granulated material toward the openings 71, by which time the material to be crushed, has been reduced to'a fine dust.

'Hereinbefore I have disclosed a device in which the axis of oscillation of the weight J has been shifted in a horizontal plane by hand power, but in Figs. '5, 6 and 7 1 disclose means whereby the said axis may be shifted by mechanical means; one case, that of Figs. 5 and 6 disclosing means whereby the axis of oscillation of the weight'J may be reciprocated under andcontrolled by the vibratory, movement of the perpendicula'rs F and F of the rocking bed E, and in Fig.

7, disclosing a means; whereby the said perpendicularsF and F and the: rocking bed E may be controlled by the oscillation of the' freely'swingingweight J. And I now wish'it'understood that the vibration of the arms F 5 and .F maybe accomplished by other means than those shown in Figs. 5, 6,

and 17." "For-"instance, solenoid coils and i cores with proper electrical connections may be substituted for the steam cylinders and mechanism disclosed in said figures without departing from the spirit or scope of my invention. And, moreover, arms extending longitudinally beyond the ends of the rocker bed E and connected to proper motive power means may be employed to impart the proper movement to the said rocker bed and the requisite oscillation to the weight J, through the required shifting of the axis of oscillation of the said weight J by reciprocating the ends of the perpendicular arms F and F.

As an illustration of the employment of my device may be mentioned the use as a coffee grinder or crusher in coffee stores and the like in which instance the bed frame A,

with its chutes L, and its crusher plates 13 r with certain of the openings or 71 are employed. The rocker bed E and its rollers F and studs G together with the suspended weight J, freely depending from the shaft G, the latter journaled at the upper end of the arms F and F are essentials. By an occasional movement of the hand at the handle end or member 62 of one of the arms F or F a sequential shifting of the axis of oscillation of the weight J is obtained, and the swinging, oscillation, or pendulum motion of the weight J is maintained, and, a crushing action between the rocker bed E and the top surface of the crushing plates 13 is secured.

I have already mentioned that the rocker bed E has a compound rocking, and endwise movement. This endwise movement is attained by the rollers F moving vertically in the guiding slots C, 0. As the bed E rolls on the crusher plate 13, the center of rotation of the bed would naturally shift either to the right or to the left, as the case may be; but on account of these rollers F moving in said slots C, C, this reciprocating movement or shifting of the center of rotation is translated into" a vertical movement thereof, which causes a slight dragging or scraping movement of the curved surface of the rocker bed on the horizontally disposed plane surface of the crusher plate 13, which movement materially assists in disintegrating .the material placed between these two surfaces, and in moving the said material from the ends of the crusher plate toward the center thereof.

In Figs. 5 and 6 are illustrated means for mechanically shifting the arms F and F, to reciprocate the axis of oscillation of the weight J, the said movement being controlled by a lever 100, pivoted at one end to the frame work of the machine and with the other end slidably embracing the shaft G, the said lever being alternately acted upon by pistons 101 and 102 of cylinders 103 and 104, which pistons are controlled by valves 105 and 106, actuated by a bar 7 107, having stems 108 and 109, which are alternately engaged by the vibration of the lever 100 in an evident manner.

In Fig. 7 is shown the suspension rod for the weight J as a solid bar I-l, having an upwardly projecting arm H, which is adapted to control the valves of the cylinders 106 or 105, instead of the same being directly controlled by the lever 100. By this construction the oscillation of the weight J controls the shifting of the axis of oscillation of said weight in a manner readily understood.

While I have herein disclosed in detail the mode of practising my invention, I do not hereby limit myself to the particular structure described, and reserve to myself the right to make such changes in structure and detail as may be permitted under a broad interpretation of the claims herewith appended.

I have hereinbefore disclosed the preferred mode of practising my invention, but I reserve the right to make such and any changes as might occur to one skilled in the art to which this invention appertains, or to make any and all such alterations as may be permitted under the doctrine of equiva lents.
